The Kielanowski Institute of Animal Physiology and Nutrition conducts fundamental and applied research in the fields of farm- and laboratory animal physiology and nutrition. The projects include studies on the endocrinology of growth, development, and reproduction, on neuroendocrinology, as well as on the metabolism and utilization of nutrients and biologically active substances from feeds.Important topics of research are the development of digestive tract structure and function in newborn and growing animals and the symbiotic microorganisms colonizing the gastrointestinal tract of herbivorous mammals.The aim of innovative research undertaken in recent years is the improvement of the health-promoting qualities of poultry, pork, and lamb meat by reducing their fat content and improving their fatty acid profiles.
